Paratrechina Zanjensis
''Paratrechina zanjensis'' is an African species of ant in the genus ''Paratrechina''. It is one of two species in the genus, the other being the longhorn crazy ant (''Paratrechina longicornis''). Habitat and distribution The species in known from Tanzania, Angola and Mozambique. Very little is known about the natural history of ''Paratrechina zanjensis''; the 23 specimens collected in the Mkuju River region of the Selous Game Reserve in Tanzania were all found in 48-hour pitfall trap samples while none were found in the 40 Winkler-extracted leaf litter samples collected during daytime along the same transects. The two Tanzanian sites in which ''Paratrechina zanjensis'' were found were representative of mature dry miombo woodland, while they appeared to be absent from both dry and moist closed canopy forest sites nearby. The Angola and Mozambique specimens were also collected in miombo woodlands; this, in combination with the absence of ''Paratrechina zanjensis'' from 15 forest ...

Nylanderia
''Nylanderia'' is a large genus of ants in the subfamily Formicinae. The genus has a nearly cosmopolitan distribution with species inhabiting a wide array of habitats in almost all geographic regions. ''Nylanderia'', currently containing over 110 species, is an ecologically important genus, with some species reported as being invasive. The ants are small to medium in size and range in color from pale yellow to black. Taxonomy The genus was first described as a subgenus of ''Prenolepis'' by Emery (1906), a status he revised a couple of years later when he placed it as subgenus of ''Paratrechina'' (Emery, 1925). Wheeler (1936) raised ''Nylanderia'' to genus, where it remained until Brown (1973) provisionally placed it as a junior synonym of ''Paratrechina'', a status which was later confirmed by Trager (1984). ''Nylanderia'' was finally revived from synonymy and restored at the rank of genus by LaPolla, Brady & Shattuck (2010). Until 2010, most ''Nylanderia'' species were placed ...

Propodeum
The propodeum or propodium is the first abdominal segment in Apocrita Hymenoptera (wasps, bees and ants). It is fused with the thorax to form the mesosoma. It is a single large sclerite, not subdivided, and bears a pair of spiracles. It is strongly constricted posteriorly to form the articulation of the petiole, and gives apocritans their distinctive shape. There may be a suture between the propodeum and the thorax, like in Symphyta Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay ... or not, and the presence or absence of such suture can aid in identifying specimens. In molluscs Propodium is the anterior (frontal) part of the foot of a mollusk. References Insect anatomy Gastropod anatomy {{insect-anatomy-stub ...

Mesonotum
The mesothorax is the middle of the three segments of the thorax of hexapods, and bears the second pair of legs. Its principal sclerites (exoskeletal plates) are the mesonotum (dorsal), the mesosternum (ventral), and the mesopleuron (lateral) on each side. The mesothorax is the segment that bears the forewings in all winged insects, though sometimes these may be reduced or modified, as in beetles (Coleoptera) or Dermaptera, in which they are sclerotized to form the elytra ("wing covers"), and the Strepsiptera, in which they are reduced to form halteres that attach to the mesonotum. All adult insects possess legs on the mesothorax. In some groups of insects, the mesonotum is hypertrophied, such as in Diptera, Hymenoptera, and Lepidoptera), in which the anterior portion of the mesonotum (called the mesoscutum, or simply "scutum") forms most of the dorsal surface of the thorax. In these orders, there is also typically a small sclerite attached to the mesonotum that covers the wing ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pronotum
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also *Glossary of entomolo ...

Eastern Arc Mountains
The Eastern Arc Mountains is a chain of mountains found in Kenya and Tanzania. The chain runs from northeast to southwest, with the Taita Hills being in Kenya and the other ranges being in Tanzania. They are delimited on the southwest by the fault complex represented by the Makambako Gap that separates them from the Kipengere Range. To the northeast, they are delimited by more recent volcanism represented by Mount Kilimanjaro. The chain is considered a Tentative World Heritage Site. Mountain ranges The Eastern Arc Mountains forms a roughly crescent-shaped arc and consists of: # Taita Hills # North and South Pare Mountains # East and West Usambara Mountains # Nguru Mountains # Ukaguru Mountains # Uluguru Mountains # Uvidunda Mountains # Rubeho Mountains # Malundwe Mountain # Udzungwa Mountains # Mahenge Mountains Geology These mountain ranges are the oldest in East Africa, and though physically separated from each other, share a similar geomorphology and ecology. They were for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miombo Woodland
The Miombo woodland is a tropical and subtropical grasslands, savannas, and shrublands biome (in the World Wide Fund for Nature scheme) located primarily in Central Africa. It includes four woodland savanna ecoregions (listed below) characterized by the dominant presence of ''Brachystegia'' and ''Julbernardia'' species of trees, and has a range of climates ranging from humid to semi-arid, and tropical to subtropical or even temperate. The trees characteristically shed their leaves for a short period in the dry season to reduce water loss and produce a flush of new leaves just before the onset of the wet season with rich gold and red colours masking the underlying chlorophyll, reminiscent of autumn colours in the temperate zone. The woodland gets its name from ''miombo'' (plural, singular ''muombo''), the Bemba word for ''Brachystegia'' species. Other Bantu languages of the region, such as Swahili and Shona, have related if not identical words, such as Swahili ''miyombo'' (singular ...

Leaf Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is ...

Pitfall Trap
A pitfall trap is a trapping pit for small animals, such as insects, amphibians and reptiles. Pitfall traps are a sampling technique, mainly used for ecology studies and ecologic pest control. Animals that enter a pitfall trap are unable to escape. This is a form of passive collection, as opposed to active collection where the collector catches each animal (by hand or with a device such as a butterfly net). Active collection may be difficult or time-consuming, especially in habitats where it is hard to see the animals such as thick grass. Structure and composition Pitfall traps come in a variety of sizes and designs. They come in 2 main forms: dry and wet pitfall traps. Dry pitfall traps consist of a container (tin, jar or drum) buried in the ground with its rim at surface level used to trap mobile animals that fall into it. Wet pitfall traps are basically the same, but contain a solution designed to kill and preserve the trapped animals. The fluids that can be used in these trap ...
